Yep! You guys have got it right. Everything that you do determines your health. This includes your snacking habits, whether you eat out or homecooked food, and whether you get the right amount of nutrients. It sounds really complicated but trust me you just have to get the hang of it. You'll have to do a bit of research in the start, and you might even have to look at a few text books to see whats best for your health, but its going to be worth it in the end. Essentially, I'm just saying that we all should learn about bodily needs to be able to supply the right ingredients for good health. Theres a ton of information online about everything from getting proper sleep to exercising to eating well.

 I suggest that we start like an accountability group where we assign a reading each week and then discuss it at the end. What do you guys say?
